When in use, the device avoids 110 I bending the hose at the point of attachment with the hydrant, since the universal joint provided by the cooperating globular portions 20 and 17 provides for universal movement.

In the modication shown in Figures 5 and 6, the coupling member 12a is identical with the coupling member 12 whereit connects with the coupling element 10, but is modified at that end which connects with the flexible tubular member 11a, being alternately bulged and contracted circumferentially as indicated at 28. The flexible tubular member lla in this form of the invention is provided with an internal bead 29 which seats in the contracted portion between the two bulges of the coupling member 12a but is exteriorly provided with the bead 30 which seats in an annular bulge 31 of the clamp member 32, the latter being in the form of a cap slidable over the neck portion of the coupling member 12a but receivable over the end of the exible tubular member 11a, after the coupling member l2 has been inserted into the latter Where its bead 29 will engage in the contracted portion of the coupling member. In this form of the invention, the connection with the hose may be in the same manner as the exible tubular member is connected with the coupling member 12a. or it may be in the form illustrated in Figure 1 for connecting the hose to the device.

The flexible tubular members 1l and 11a may have their Walls reinforced to prevent acute bends but at the same time leave them resilient, such reinforcement being in that portion of the walls of the tubular members comprehenfied between the connected ends of the coupling members 12 and 14.

The invention having been described, what is claimed as new and useful is:

1. A device for the purpose indicated comprising a exible tubular member and means for coupling it to a fire hydrant and comprising a universal joint, and a coupling inember at the extremity of the exible tubular element, the coupling member being of tubular form and enlarged for insertion in the extremity of the hose, and a clamp ring slidable on the coupling member and engageable over the extremity of an attached hose, the hose being provided with a bead at said extremity and the clamp ring being formed with an angular bulged portion serving as a seat for the bead and a flared skirt portion extending from the bulged portion and serving to direct the bead into the bulged portion.

2. A device for the purpose indicated comprising a flexible tubular member and means for coupling it to a fire hydrant and comprising a universal joint, and a coupling member at the extremity of the exible tubular element, the coupLng member being of tubular form and enlarged for insertion in the extremity of the hose, a clamp ring slidable on the coupling member and engageable over the extremity of an attached hose, and a bead attachable to the extremity of the hose and comprising a rubber ring with internally projecting spurs engageable in the Wall of the hose, thev bead seating in an annular bulge formed in the clamp ring.
